Archaeology Survey at Historic Jamestown Rediscovery
The archaeology team at Jamestown, Virginia conducts a GPR survey over the 1607 Burial excavation site - the final resting place for many of the original 104 men and boys who landed in Virginia in the Spring of 1607. Using the StructureScan Mini XT, mapping the orientation of the remains minimizes the potential for damaging the more sensitive skeletal elements, like the cranium, during the excavation process.

Archaeological Survey at Henry Whitfield House
Archaeological survey using UtilityScan® at a 1639 stone garrison house built during the Pequot War in the Connecticut Colony. The Henry Whitfield House is a ca. 1639 stone garrison house, and is one of the earliest current standing Euro-American houses in North America and the oldest in Connecticut. While the house served as a private residence for over 260 years, it was purchased by the State of Connecticut in 1900 and renovated as a museum; the Whitfield House is not only an early American house, but also an early historical museum. The GPR survey provided evidence for a network of utility lines, pipes, buried paths, a Colonial Revival Garden, remnants of the house's previous ell foundation, a cistern, and several unknown archaeological features.

GPR Survey Inside Concrete Tunnel Liner
Collected miles of GPR profiles using SIR® 4000 and 900 MHz antenna to characterize the liner at several angles around the circular tunnel. The antenna was custom-mounted to a pivot point on the ATV loading deck to be able to access and collect the profiles at various angles. The totally dark tunnel was only illuminated by the ATV headlights and headlamps.

Geology Survey on Baffin Island in Canada
Geological survey to identify and delineate underground ice bodies along a proposed railroad alignment. The length of the alignment was approximately 70 km. The investigation was a combination of hand-tow and snowmobile-tow surveying, and involved snowmobile and helicopter deployment. The equipment used provided the investigation depth up to 30 m in the permafrost.

Utility Locating Survey at Transit Depot in Indonesia
The purpose of this survey was to accurately locate leaks in an underground hydrant pipe. Ground Penetrating Radar (GPR) is commonly used in water leakage mapping to detect and visualize subsurface anomalies that may indicate water infiltration. GPR identifies areas with differing moisture levels, voids, and other irregularities that could signify leaks.
